    Cotinus coggygria Scop. (Anacardiaceae) is an important ornamental tree with beautiful characteristics that is grown in China. In this study, the complete plastid genome of C. coggygria was sequenced and assembled. This genome was 158,843 bp in size and presented a typical tetrad structure, consisting of a large single-copy region (87,121 bp), a pair of inverted repeat regions (26,829 bp), and a small single-copy region (18,064 bp). A total of 134 genes were annotated, including 88 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. We observed a deletion that caused the loss of the rpl32 gene, and a small expansion of IR regions resulted in the trnH gene accessing IR regions; two copies were obtained. Phylogenetic analysis showed that C. coggygria was most closely related to Pistacia, with 100% bootstrap support within Anacardiaceae. In this study, we report the plastid genome of Cotinus species for the first time, which provides insight into the evolution of the plastid genome in Anacardiaceae and promotes the understanding of Cotinus plants.
